Tuition & Financial Aid

Tuition for the 2022-2023 school year

is $54,950. This amount includes standard fees for textbooks and supplementary materials, annual Fall Trips, and a copy of the school yearbook.


Tuition can be paid in full, or in 10-month installments.  You will select a payment plan when you complete your Enrollment Agreement.

Additional Fees


There is an additional $1,250 Program Fee each year, and a $280 Senior fee in the 12th-grade year.  


Athletics & Academic support

Further fees are assessed for participation in specific athletics and academic support programs.

Lunch & Transportation

The Marin School provides access to a student lunch program for an additional fee. Occasionally, a class field trip could be scheduled that may include a small fee.

We are committed to maintaining socio-economic diversity in our community by helping families afford a TMS education.

Over 30% of our students receive some amount of need-based aid. We know that every family's financial situation is unique and we take care to consider every application carefully.


Financial aid decisions are always made entirely independent of the admissions process. Because we have limited resources, some students may be accepted for admission, but remain on a waitlist for financial assistance.


The Marin School partners with  School and Student Services (SSS) to process financial aid applications. SSS is a service of the National Association of Independent Schools (NAIS). Families applying for financial assistance must meet all deadlines for submitting appropriate forms. Failure to meet Financial Assistance application deadlines may result in reduced or denied financial assistance.

Apply for Financial Aid

To begin your financial aid application, please follow these steps:

The Marin School partners with School and Student Services (SSS) in our financial aid process. To begin your financial aid application, you will complete the SSS Parents’ Financial Statement (PFS).

By submitting a PFS, you’re granting SSS permission to analyze your financial information. Using their unique methodology, they estimate the amount you can contribute to school expenses and forward that estimate to the appropriate schools. This confidential process is one form, for one fee, for any number of applicant children, for any number of schools.

Learn more about the decision-making process, and how the EFC is calculated.

Financial Aid Deadlines: 


Parent Financial Statement (PFS):  January 12th, 2023

2022 Tax Documentation (New & Returning Families): February 13, 2023

Parent FA Responses: March 23, 2023

  • Create your Family Portal account with your email address and a password. If you applied for financial aid last year, log into the Family Portal as a Returning Family using the same email address and password. Complete a PFS for Academic Year 2022-23. You can log out of the portal at any time and return later to finish it.

  • Plan ahead!  The PFS is a comprehensive application that will take some time to complete. Give yourself the time you need by not waiting until the deadline approaches. It’s important to note the difference between the deadlines for admission and financial aid applications.

  • Upload supporting documents electronically into your PFS:  a signed copy of your 2022 IRS 1040 Tax Statement (be sure to include all supporting schedules and forms). Please note the following:

    • If you do not have your 2022 tax return, complete the PFS using your most recent tax return. When the requested tax forms arrive, such as W2s or 1040s, log back in and upload them by the deadline. We also recommend that you review resources that SSS has put together to help families with their financial aid process:

    • We understand that not all documents will be ready in February. We will accept an informed estimate or draft of the 2022 tax return if necessary. Please be sure to clearly indicate “Draft” or “Estimate.” A 2020 1040 must be submitted to be considered. 

    • If waiting on K-1 requires you to file an extension, please upload a draft tax return clearly titled or marked “Draft” or “Estimate.”  


If you have any questions, please reach out to SSS directly, as they will be able to provide the timeliest and most precise responses.
